I always fry squash in an electric skillet. Preheat skillet to 350 degrees add oil, just enough to lightly cover the bottom. Combine squash, cornmeal and onions in a zip-lock bag and shake. Carefully put squash/onion mixture into skillet. Cover with lid. Turn squash when browned – at this point you may need to add more oil. (just a little, as needed) While cooking; you will also need to tilt your lid to let the steam escape.

Right before squash is done sprinkle with salt, pepper and onion powder.
